oct/nov 1999 Q.18 and Q.37 is there something wrong in the ms or not?
may/june 1999 i dont understand Q.18 and Q.22
plz help and ty :D
For 18, i think it's B, I don't know about the ms.
For 37, Yes the ms is wrong, it is B not D!
June 1999, 18- the valve (or whtvr u call it) allows escape of CO2, but prevents entry of O2...in Chemistry! so answer is B.
22- it is C; auxin accumulates on the darker side--> but B will still have a bit of auxin at the top (observe that the label line includes the region of cell elongation)
btw, i did this mistake before!

abt 18 i think it's correct :S
37 is wrong it's B
18 : Co2 leaves as it is anaerobic respiration
22 : auxins acumulate in the darker side and produced from the tip ,so C is the side where light is ..
